Summaries for SIAH2 Gene

Entrez Gene Summary for SIAH2 Gene

  • This gene encodes a protein that is a member of the seven in absentia homolog (SIAH) family. The protein is an E3 ligase and is involved in ubiquitination and proteasome-mediated degradation of specific proteins. The activity of this ubiquitin ligase has been implicated in regulating cellular response to hypoxia. [provided by RefSeq, Jul 2008]

GeneCards Summary for SIAH2 Gene

SIAH2 (Siah E3 Ubiquitin Protein Ligase 2) is a Protein Coding gene. Diseases associated with SIAH2 include hypoxia. Among its related pathways are L1CAM interactions and L1CAM interactions. GO annotations related to this gene include ubiquitin-protein transferase activity and ubiquitin conjugating enzyme binding. An important paralog of this gene is SIAH3.

UniProtKB/Swiss-Prot for SIAH2 Gene

  • E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Mediates E3 ubiquitin ligase activity either through direct binding to substrates or by functioning as the essential RING domain subunit of larger E3 complexes. Triggers the ubiquitin-mediated degradation of many substrates, including proteins involved in transcription regulation (POU2AF1, PML, NCOR1), a cell surface receptor (DCC), an antiapoptotic protein (BAG1), and a protein involved in synaptic vesicle function in neurons (SYP). Mediates ubiquitination and proteasomal degradation of DYRK2 in response to hypoxia. It is thereby involved in apoptosis, tumor suppression, cell cycle, transcription and signaling processes. Has some overlapping function with SIAH1. Triggers the ubiquitin-mediated degradation of TRAF2, whereas SIAH1 can not. Promotes monoubiquitination of SNCA.
